wp-block-development

Covers the full lifecycle of WordPress Gutenberg block development: creating and registering blocks, editing block.json metadata, handling attributes and serialization, adding dynamic rendering via render.php, and managing deprecations to avoid "Invalid block" errors. Works with @wordpress/scripts and @wordpress/create-block build tooling. Block development has enough moving parts (apiVersion, serialization contracts, asset scoping, deprecation chains) that skipping a structured procedure reliably produces broken saves or editor warnings — this skill walks through each step in the right order.
